NX1P2 Motion Control change output device with code
BrunoRamos posted a topic in NJ Series / Sysmac Studio
Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems. Best Regards, BR -
Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you.. I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required? Thank you for reading and look forward to your response :)

Hi, I'm looking for help with the string exchanging between GT25 and AB CompactLogix. I'm reading recipe data from SQL via MES interface to the local devices such as GD3000. I want to move the string held in the registers GD3000-3009 (20 characters) to the string tag in the Allen Bradley. The problem is that in the scripting I cannot enter the AB Tag, because when I imported the CSV with the string tags their data type is STRING, and the scripting in GOT accepts only numerical datatypes such as WORD, etc. Has anyone found a way to handle that?

Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual: OD5000, 8021391 (sick.com) (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw

Hello experts, i want to connect 9 FX3U units with one Q cpu base PLC unit over wifi, can you plz share the configuration details.

Good day fellow PLC ninjas! I have a question/ concern which I would love your opinions on. We have 3 FX3U PLC’s+ENET cards. Two of the 3 PLC’s move around in an EMS trolley. The other is a ‘base station’ with a GOT2000 connected via Ethernet. Base PLC IP = 192.168.1.11 HMI IP = 192.168.1.31 Carrier 1 IP = 192.168.1.61 Carrier 2 IP = 192.168.1.62 I have programmed the base PLC to use Active communication; we are using fixed buffer communication to send and receive data to/ from the Carriers. The carriers are set up as Fullpassive ‘slaves’. This part works well and the update time changes (using a counter in the base station) from 1s to 100ms (because it enters a different work station). My issue is the following: using a network sniffer (WireShark), I pick up plenty of re-transmits and sequence number errors coming from the base PLC’s ENET card. This is troublesome and causes delays when the update time is required to be fast (100ms). I am sending and receiving 10 words of data. The wifi seems stable, and there is minimal noise in the area. The power has been turned down and the antennas used are suited well for the application. The antennas are at a similar height to minimize possible loss of signal. I have LOS (line-of-sight) to the carriers at all times; to at least one of the antennas (I am using 802.11n). Has anyone picked up issues or found settings which can be used for comms over wifi? I can easily do this using a S7-1200 Siemens PLC and have done so using 12x S7-1200 clients and 2 AP’s with 1 base PLC. I have also successfully done this using 8xFX3U client with a System Q base PLC. My suspicion is that the delay in reading and writing to/ from the BFM in the ENET card is causing this. I am not sure that if I change to a FX5U will help. The communication cards on the Mitsubishi PLC’s seem very limited. Does anyone have any technical details on the access times between the CPU and communications cards’ BFM? Help is as always, appreciated.

Hello! I'm trying to connect my QD75M2 with a MR-J2S40B1 Servo amplifier with an SSCNET cable. The problem is when I try to turn on the Servo ON/OFF on the Intelligent function in GxWorks2, an error occurs saying the servo amplifier is disconnected with my QD75M2. I'm confident that I've wired it properly. What could be the problem? Hoping you might help. Thank you.

Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.

Hey! Is there any possibility to acces the PLC variables in GXWorks from another program? Like I want to read and write the I/O-s or Merkes in the Mitsubishi PLC from another program Could someone help me with this? Thank you!

Hello! Is there any possibility to connect a Mitsubishi PLC to a program like Siemens Plant Simulation? With Siemens PLC I can do it through OPC UA protocol, or Shared Memory with SIMIT, or stuff like that. But I would need to do it also with Mitsubishi PLC. Can I use for example OPC Server? I couldn't find out, if Mitsubishi PLC-s have that function built-in. (I have a L02 and a FX3S COU, either of them would be great.) Thank you!

My HP laptop will lose communication with Mitsubishi PLC occasionally after removing ethernet cable to download from WiFi. Our company limits the ability to use the wi-fi when I have an ethernet cord connected to my laptop, it has to do with security. If I am connected to the Mitsubishi PLC, then want to download another file from our autosave, which we connect through the wifi, I have to remove the ethernet cord from my HP laptop to enable the ability to go wireless, however sometimes when I attempt to go online with the PLC after I re-connect my ethernet cable, GX developer will not allow it. I can ping the plc and even go online with other PLCs on the network, but for some reason, the one I was connected to will not connect. I restart my computer and even re-download the file again from autosave but no joy. Its not until an unknown amount of time that it will allow me to re- connect, its as if I lose the socket connection on the plc and it needs time to reopen. I talked to our IT department and they have no ideas. Thank you in advance for any help on this matter.

Hello. I have a system in which an A1S68AD card is used, that card has been damaged . I replace that damaged card with the new A1S68AD card with same wiring and same setting of dip switch. But at channel number 3 there is a RTD connected which gives 4-20 mA signal. But in Plc at channel number 3 the data register is showing -2400 fixed value all the time and in actual the temperature is varying. But PLC SHOWS FIXED VALUE OF -2400. PLEASE HELP ME OUT.

Difference between Active immediate and passive immediate homing ?
Joseph 0028 posted a topic in Allen Bradley / Rockwell Automation
What is the difference between Active Immediate homing and passive immediate homing ? Does Motion servo axis have to be turned ON for active immediate and turned OFF for passive immediate homing ?. -
Do we need to manually unlatch motion instruction bits ?
Joseph 0028 posted a topic in Allen Bradley / Rockwell Automation
I have seen some programs in which they manually unlatch all bits like in figure 1, and in some programs they don't do that. The instruction help page, ladder execution says that in pre-scan .EN, .DN, .ER, .IT bits are cleared to false So do we need to unlatch all these bits before giving a motion command like MAM ? -
Dear all, I have a FX2N-20MR chinese semi-clon of a Mitsubishi PLC. It has only a serial DB9 port that cannot be removed or exchanged (which is possible in the Mitsubishi original PLC). I wonder if I can make a simple SCADA system using that port and just one computer. I am reading this post: https://forums.mrplc.com/index.php?/topic/9653-fx-series-and-modbus/ And I am wondering how I can do what it is suggested there in the second message: to use a free FB block, available in GX IEC (but not in GX Developer), which will communicate modbus via a standard RS232 BD board. Later on it mentions a library called ModbSFX. That message is from 15 years ago so I am wondering if now there is some other way to do it, perhaps some other software has that functionality? I don't have GX IEC. I am a student trying to make a project so I would like a cheap and simple solution. Any help to do so will be very welcome. Thanks Regards Marcelo

NC (Normally Closed) contact not working on mitsubshi HMI
ClaytonOLeary posted a topic in Mitsubishi
Hi guys, I am using a GT2107-wtsd HMI and a FX5U-32M PLC with gx works3 and designer3, i setup some simple ladder code to test that everything works, but i cannot get a normally closed contact to open when i press the button on the HMI and make the light turn off? screenshot below shows the code and the HMI buttons, when just looking at the HMI screen, all lights should be off with the exception of light number 2 as it is conected to a Normaly closed contact and i want it to open when i press the button on the HMI beside LT2 (light 2). I cant seem to get it to work.. please help, thanks. -
Hello, I am new to the programming of logic controllers. I have a Chinese FX3U 24 inputs and outputs with analog in and outputs. I am trying to teach myself the basics of the programming but I am stuck at the analog part. what I am looking to do is create a program so that when a 12v battery bank voltage drops and rises it can trigger other outputs. I have a voltage divider which outputs 1/5 of the input. Thanks for your help in advance. Ben.

The PC (process complete) bit of MAS command does not clear
Parya posted a topic in Allen Bradley / Rockwell Automation
Hello everyone, I have this weird problem that the PC (process complete) bit of MAS command does not clear after a cycle time. As you may probably see in the picture attached when the desired torque has been reached, the servo has to be stopped using MAS command; however, this is good only for one cycle!! The PC bit will remain on even when the whole sequence gets unlatched/reset. I have to manually reset this bit. I was wondering if you could help me with this issue, please? Thank you! -

Hi guys, im just looking for some help if possible, I am trying to setup a HMI (2107-wtsd) but GT Designer3 does not have this model nor does it have any 2107 models in the GOT type dropdown. How can i get my model to show? I have tried setting the GOT type as a G2105 and the GT softGOT2000 and these did not work, the HMI is on a white screen with install package data but i cannot do this if it is not in the GOT dropdown correct? I have attached some pictures to show. the HMI is connected to the PLC via ethernet and the laptop is connected to the HMI via usb I am very new to this so we are using test benches so if anything looks wrong i am very sorry

Good day everyone, I am working on a problem on a Mitsubishi Q series PLC and motion system. The system consist of a Q12H PLC CPU and 2 x Q173CPUN Motion CPUs. The first motion controller controls 23 x MR-2JS-_B Servodrive and thesecont motion controller CPU controls 6 x MR-2JS-_B Servodrives. They are all using SSCNET1 system.The machine have been working fine all along until the machine stoped for 3 months because we were waiting for one spare part that was coming from oversees during covid lockdowns. When we restarted the machine, the servodrives could not home. When we were busy checking for the problem and before finding the problem, the machine just started homing. This keeps on happening over and over. Everytime you stop the machine overnight, it just stop working then when you are busy troubleshooting, it just come to like. In the time when it is not responding, we figured out that when we jog the servodrive controlled by second Motion controller CPU for the HMI, the drives jog fine but the servodrives controlled by first motion controller CPU does not respond. I have tried jogging the servodrives indipendently using Setup161E and they move . I even changed the motion CPU but to no success. When you monitor using MT Developer 2, the are no errors. Is there anyone who might have an idea on what might be the probable cause
